A conceptual model for group support systems in local councils

This paper proposes a conceptual model of a context-aware group support system (GSS) to assist local council employees to perform collaborative tasks in conjunction with inter- and intra-organisational stakeholders. Most discussions about e-government focus on the use of ICT to improve the relationship between government and citizen, not on the relationship between government and employees. This paper seeks to expose the unique culture of UK local councils and to show how a GSS could support local government employer and employee needs.

Local and average structure in zinc cyanide: towards an understanding of the atomistic origin of negative thermal expansion

Neutron diffraction at 11.4 and 295 K and solid-state 67Zn NMR are used to determine both the local and average structures in the disordered, negative thermal expansion (NTE) material, Zn(CN)2. Solid-state NMR not only confirms that there is head-to-tail disorder of the C≡N groups present in the solid, but yields information about the relative abundances of the different Zn(CN)4-n(NC)n tetrahedral species, which do not follow a simple binomial distribution. The Zn(CN)4 and Zn(NC)4 species occur with much lower probabilities than are predicted by binomial theory, supporting the conclusion that they are of higher energy than the other local arrangements. The lowest energy arrangement is Zn(CN)2(NC)2. The use of total neutron diffraction at 11.4 K, with analysis of both the Bragg diffraction and the derived total correlation function, yields the first experimental determination of the individual Zn−N and Zn−C bond lengths as 1.969(2) and 2.030(2) Å, respectively. The very small difference in bond lengths, of ~0.06 Å, means that it is impossible to obtain these bond lengths using Bragg diffraction in isolation. Total neutron diffraction also provides information on both the average and local atomic displacements responsible for NTE in Zn(CN)2. The principal motions giving rise to NTE are shown to be those in which the carbon and nitrogen atoms within individual Zn−C≡N−Zn linkages are displaced to the same side of the Zn···Zn axis. Displacements of the carbon and nitrogen atoms to opposite sides of the Zn···Zn axis, suggested previously in X-ray studies as being responsible for NTE behavior, in fact make negligible contribution at temperatures up to 295 K.

Terrorist transgressions: gendered representations of the terrorist in visual culture

The aim of Terrorist Transgressions is to analyse the myths inscribed in images of the terrorist and identify how agency is attributed to representation through invocations and inversions of gender stereotypes. In modern discourses on the terrorist the horror experienced in Western societies was the appearance of a new sense of the vulnerability of the body politic, and therefore of the modern self with its direct dependency on security and property. The terrorist has been constructed as the epitome of transgression against economic resources and moral, physical and political boundaries. Although terrorism has been the focus of intense academic activity, cultural representations of the terrorist have received less attention. Yet terrorism is dependent on spectacle and the topic is subject to forceful exposure in popular media. While the terrorist is predominantly aligned with masculinity, women have been active in terrorist organisations since the late 19th century and in suicidal terrorist attacks since the 1980s. Such attacks have confounded constructions of femininity and masculinity, with profound implications for the gendering of violence and horror. The publication arises from an AHRC networking grant, 2011-12, with Birkbeck, and includes collaboration with the army at Sandhurst RMA. The project relates to a wider investigation into feminism, violence and contemporary art.

Social innovation in local food in Japan: Choku-bai-jo markets and Teikei cooperative practices

The working paper depicts two innovative examples from Japan of the direct supply of food, which involves the development of closer producer-consumer relations, as well as closer producer-producer networks. Choku-bai-jo and Teikei networks are considered as examples of practices implicated in alternative food networks (AFNs). One example has become a quasi-public endeavour and is seen by the Japanese state as a legitimate part of rural development and is promoted in support of small producers. The other is borne from consumer concern over food quality and, despite its long-lived status, this arrangement remains marginal and with little institutional or governmental support. A model which blends the organization and aims of both examples holds potential for a more sustainable eco-economic future.

The late Roman field army in Northern Britain? Mobility, material culture and multi-isotope analysis at Scorton (N. Yorks)

At Hollow Banks Quarry, Scorton, located just north of Catterick (N Yorks.), a highly unusual group of 15 late Roman burials was excavated between 1998 and 2000. The small cemetery consists of almost exclusively male burials, dated to the fourth century. An unusually large proportion of these individuals was buried with crossbow brooches and belt fittings, suggesting that they may have been serving in the late Roman army or administration and may have come to Scorton from the Continent. Multi-isotope analyses (carbon, nitrogen, oxygen and strontium) of nine sufficiently well-preserved individuals indicate that seven males, all equipped with crossbow brooches and/or belt fittings, were not local to the Catterick area and that at least six of them probably came from the European mainland. Dietary (carbon and nitrogen isotope) analysis only of a tenth individual also suggests a non-local origin. At Scorton it appears that the presence of crossbow brooches and belts in the grave was more important for suggesting non-British origins than whether or not they were worn. This paper argues that cultural and social factors played a crucial part in the creation of funerary identities and highlights the need for both multi-proxy analyses and the careful contextual study of artefacts.

An assessment of the impact of local processes on dust lifting in martian climate models

Simulation of the lifting of dust from the planetary surface is of substantially greater importance on Mars than on Earth, due to the fundamental role that atmospheric dust plays in the former’s climate, yet the dust emission parameterisations used to date in martian global climate models (MGCMs) lag, understandably, behind their terrestrial counterparts in terms of sophistication. Recent developments in estimating surface roughness length over all martian terrains and in modelling atmospheric circulations at regional to local scales (less than O(100 km)) presents an opportunity to formulate an improved wind stress lifting parameterisation. We have upgraded the conventional scheme by including the spatially varying roughness length in the lifting parameterisation in a fully consistent manner (thereby correcting a possible underestimation of the true threshold level for wind stress lifting), and used a modification to account for deviations from neutral stability in the surface layer. Following these improvements, it is found that wind speeds at typical MGCM resolution never reach the lifting threshold at most gridpoints: winds fall particularly short in the southern midlatitudes, where mean roughness is large. Sub-grid scale variability, manifested in both the near-surface wind field and the surface roughness, is then considered, and is found to be a crucial means of bridging the gap between model winds and thresholds. Both forms of small-scale variability contribute to the formation of dust emission ‘hotspots’: areas within the model gridbox with particularly favourable conditions for lifting, namely a smooth surface combined with strong near-surface gusts. Such small-scale emission could in fact be particularly influential on Mars, due both to the intense positive radiative feedbacks that can drive storm growth and a strong hysteresis effect on saltation. By modelling this variability, dust lifting is predicted at the locations at which dust storms are frequently observed, including the flushing storm sources of Chryse and Utopia, and southern midlatitude areas from which larger storms tend to initiate, such as Hellas and Solis Planum. The seasonal cycle of emission, which includes a double-peaked structure in northern autumn and winter, also appears realistic. Significant increases to lifting rates are produced for any sensible choices of parameters controlling the sub-grid distributions used, but results are sensitive to the smallest scale of variability considered, which high-resolution modelling suggests should be O(1 km) or less. Use of such models in future will permit the use of a diagnosed (rather than prescribed) variable gustiness intensity, which should further enhance dust lifting in the southern hemisphere in particular.

Spontaneous local symmetry breaking: a conformational study of glycine on Cu{311}

Understanding the interplay between intrinsic molecular chirality and chirality of the bonding footprint is crucial in exploiting enantioselectivity at surfaces. As such, achiral glycine and chiral alanine are the most obvious candidates if one is to study this interplay on different surfaces. Here, we have investigated the adsorption of glycine on Cu{311} using reflection-absorption infrared spectroscopy, low-energy electron diffraction, temperature-programmed desorption and first-principles density-functional theory. This combination of techniques has allowed us to accurately identify the molecular conformations present under different conditions, and discuss the overlayer structure in the context of the possible bonding footprints. We have observed coverage-dependent local symmetry breaking, with three-point bonded glycinate moieties forming an achiral arrangement at low coverages, and chirality developing with the presence of two-point bonded moieties at high coverages. Comparison with previous work on the self-assembly of simple amino acids on Cu{311} and the structurally-similar Cu{110} surface has allowed us to rationalise the different conditions necessary for the formation of ordered chiral overlayers.

Two Faces of AIDS in Hong Kong: Culture and the Construction of the `AIDS Celebrity'

Since the first reported case of HIV infection in Hong Kong in 1985, only two HIV-positive individuals in the territory have voluntarily made public their seropositivity: a British dentist named Mike Sinclair, who disclosed his condition to the media in 1992 and died in 1995, and J.J. Chan, a local Chinese disc-jockey, who came forward in 1995 and died just a few months later. When they made their revelations, both became instant media personalities and were invited by the Hong Kong Government to act as spokespeople for AIDS awareness and prevention. Mike Sinclair worked as an education officer for the Hong Kong AIDS Foundation, and J.J. Chan appeared in Government television commercials about AIDS. This article explores how the public identities of these two figures were constructed in the cultural context of Hong Kong where both Eastern and Western values exist side by side and interact. It argues that the construction of `AIDS celebrities' is a kind of `identity project' negotiated among the players involved: the media, the Government, the public, and the person with AIDS (PWA) himself, each bringing to the construction their own `theories' regarding the self and communication. When the players in the construction hold shared assumptions about the nature of the self and the role of communication in enacting it, harmonious discourses arise, but when cultural models among the players differ, contradictory or ambiguous constructions result. The effect of culture on the way `AIDS celebrities' are constructed has implications for the way societies view the issue of AIDS and treat those who have it. It also helps reveal possible sites of difficulty when individuals of different cultures communicate about the issue.

War and culture studies in 2016. Putting 'translation' into the transnational?

The first issue of the 'Journal of War and Culture Studies' in 2008 mapped out the academic space which the discipline sought to occupy. Nearly a decade later, the location of war, traditionally within the nation-state, is being challenged in ways which arguably affect the analytical spaces of War and Culture Studies. The article argues for an overt engagement with a reconceptualization of the location of war as broader in both spatial and temporal terms than the nation-state. Within this framing, it identifies local 'contact zones' which are multi-vocal translational spaces, and calls for an incorporation of 'translation' into our analyses of war: translating identities, including associations of the material as well as of subjective identities, and espousing a conscious interdisciplinarity which might lead us to focus more on the performative than the representational. Putting 'translation' into the 'transnational' marks the spaces of War and culture studies as multilingual, making accessible the cultural products and cultural analyses of a much broader range of sources and reflections. The article calls for the discipline of Translation Studies to become a leading contributor to War and Culture Studies in the years to come.

Delayed local inflammatory response induced by Thalassophryne nattereri venom is related to extracellular matrix degradation

Symptoms evoked by Thalassophryne nattereri fish envenomation include local oedema, severe pain and intense necrosis with strikingly inefficient healing, continuing for several weeks or months. Investigations carried out in our laboratory showed that, in the venom-induced acute inflammation, thrombosis in venules and constrictions in arterioles were highly visible, in contrast to a notable lack of inflammatory cell. Nevertheless, the reason that the venom toxins favour delayed local inflammatory response is poorly defined. In this study, we analysed the movement of leucocytes after T. nattereri venom injection in the intraplantar region of Swiss mice, the production of pro-inflammatory mediators and the venom potential to elicit matrix metalloproteinase production and extracellular matrix degradation. Total absence of mononuclear and neutrophil influx was observed until 14 days, but the venom stimulates pro-inflammatory mediator secretion. Matrix metalloproteinases (MMP)-2 and MMP-9 were detected in greater quantities, accompanied by tissue degradation of collagenous fibre. An influx of mononuclear cells was noted very late and at this time the levels of IL-6, IL-1 beta and MMP-2 remained high. Additionally, the action of venom on the cytoskeletal organization was assessed in vitro. Swift F-actin disruption and subsequent loss of focal adhesion was noted. Collectively these findings show that the altered specific interaction cell-matrix during the inflammatory process creates an inadequate environment for infiltration of inflammatory cells.

Intense violet-blue photoluminescence in BaZrO3 powders: A theoretical and experimental investigation of structural order-disorder

Intense violet-blue photoluminescence (PL) emission at room temperature was verified in BaZrO3 (BZO) powders with structural order-disorder. Ab-initio calculations, ultraviolet-visible absorption spectroscopy and PL were performed. Theoretical results showed that the local disorder in the network-formed Zr clusters present an important role in the formation of hole-electron pair. The experimental data and theoretical results are in agreement, indicating that the PL emission in BZO powders can be related to the structural order-disorder degree in the lattice.

Local Structure and Photochromic Response in Ormosils Containing Dodecatungstophosphoric Acid

Two hybrid materials based on dodecatungstophosphoric acid (HPW) dispersed in ormosils modified with 3-aminopropiltrietoxysilane (APTS) or with N-(3-(trimethoxysilyl)-propyl)-ethylene-diamine (TSPEN) show reversible photochromic response induced by irradiation in the 200-390 nm UV range. A set of solid-state nuclear magnetic resonance (NMR) techniques was used to analyze the structural properties of the main components of these hybrids (the HPW polyanion, the inorganic matrix, and the organic functionalities). For the ormosils, the use of (29)Si NMR, {(1)H}-(29)Si cross-polarization, and {(1)H}-(29)Si HETCOR revealed a homogeneous distribution of silicon species Q ``, T(2), and T(3) for the APTS hybrid, contrasting with the separation of T(3) species in the TSPEN hybrid. The combination of (31)P NMR, {(1)H}-(31)P cross-polarization and (31)P-{(1)H} spin-echo double resonance (SEDOR) revealed the dispersion of the HPW ions in the ormosil, occupying sites with a high number of close protons (>50). Differences in the molecular dynamics at room temperature, inferred from SEDOR experiments, indicate a state of restricted mobility of the HPW ion and the surrounding molecular groups in the TSPEN hybrid. This behavior is consistent with the presence of more amino groups in the TSPEN, acting as chelating groups to the HPW ion. This hybrid, with the strong chelate interaction of the diamine group, shows the most intense photochromic response, in agreement with the charge transfer models proposed to explain the photochromic effect. Electronic reflectance spectroscopy in irradiated samples revealed the presence of one-electron and two-electron reduced polyanions. The one-electron reduced species could be detected also by (31)P NMR spectroscopy immediately after UV irradiation.

Por uma teorização das organizações de produção artesanal: habilidades produtivas nos caminhos singulares do Rio de Janeiro

The purpose of this thesis is to support the argument that workmanship production centers don¿t represent just survival strategy of social groups marginal to economical structure. Workmanship organizations are productive schemes that survived, in a parallel way, to the industrialization process, although they don¿t have been considered by the organization theory. The knowledge reserve in administration, from the traditional approach to critical studies, increased concerns on industrial organizations and business arrangements. Nevertheless, it is possible to find in Teoria da Delimitação dos Sistemas Sociais, from Guerreiro Ramos, elements to comprehend workmanship organizations as: technology, scale and sustainability, cognition, space and relationship and time. The research methodology used was bibliographic, field and documental, regarding action-research. It comes to the conclusion that, at present time, to keep it as distinct productive schemes, workmanship organizations must be associated to tourism and culture. The production must be thematic, with territorial identity, creative and sustainable, by the management of local raw material.

Política pública local e a cadeia produtiva: um estudo de caso

o trabalho apresenta a análise de um programa realizado pela Prefeitura do Município de Piraí, localizado no Estado do Rio de Janeiro, no qual visa estruturar uma política de geração de empregos a partir da cadeia produtiva de determinados produtos. A execução do programa teve início, com o planejamento e a construção de um condomínio industrial, que pudesse não só gerar empregos nas indústrias nele instaladas, mas também proporcionasse oportunidades de geração de empregos, nos estágios anteriores e/ou posteriores desta possível cadeia produtiva gerada. A participação do município então se estenderia à capacitação da população, para que esta, organizada principalmente com a estruturação de cooperativas, com apoio financeiro municipal, pudesse agregar-se aos estágios da produção. O enfoque municipal também se estendeu à forma de trabalho que demonstrasse potencialidade na região, sendo o caso do incentivo à piscicultura. Com isso, a geração de empregos se baseou em três grandes áreas: na indústria, na cooperativa e na piscicultura. Este programa proporcionou beneficios indiretos, além dos diretamente verificados, dados os objetivos preliminares, como uma conseqüente melhoria no nível de renda da população e um crescimento ordenado da região. A gestão pública enfatizou a necessidade de estabelecer uma forma de comércio integrado dos canais de produção local, visando proporcionar um nível de demanda satisfatório à manutenção dos mesmos. O beneficio criado pelo governo do município de Piraí, além da melhoria nos índices tradicionais referentes à qualidade de vida, pode ser observado numa maior interação do processo de cidadania, por meio das entidades comunitárias, associações e cooperativas.
